Abstract :
The optimization of parameters injecting into orbits based on the pattern search method is studied aiming at the condition that the calculation deviation of on-board ephemeris is gradually increased with the expansion of reckoning time. The causes of influencing on the calculation results of satellite ephemeris and generating the deviation of ground orbit injection parameters are determined through the analysis of satellite orbit calculation flow, a method for correcting the calculation of ground orbit parameters by utilizing the pattern search method is presented with consideration to the limits to on-board hardware. The method is carried out the simulation verification, which obtains good effects.
